Electro Hardware 1317M19F16440 Hex Standoff 4-40 Nylon

Product Description

The ELECTRO HARDWARE 1317M19F16440 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces in electronic assemblies. Made from nylon with a bright, uncoated finish, this standoff features a 4-40 male thread on one end and a 4-40 female thread on the other, allowing boards to be stacked or mounted securely without metal-to-metal contact. The hex body measures 3/16 inches across the flats, with an overall body length of 0.625 inches and a thread depth of 1/4 inch. It meets MIL-P-17091B fastener standards. This hardware is commonly installed by electronics technicians and field service personnel working on control boards in HVAC, electrical, and industrial equipment applications.

This standoff is suited for light-duty circuit board mounting in residential and commercial equipment enclosures. It is used wherever a non-conductive, low-profile spacer is needed to separate a PCB from a chassis or from a second board in a stacked configuration. The nylon construction provides electrical isolation and corrosion resistance, making it appropriate for indoor control panel and PCB assembly work. Technicians installing or replacing control boards in HVAC systems, electrical panels, and similar equipment will find this standoff useful for securing boards at the correct standoff height.

Key Features

• 4-40 male-female thread configuration supports stacked or single PCB mounting
• Nylon construction provides electrical isolation and eliminates galvanic corrosion concerns
• Hex body shape allows wrench-assisted installation for consistent seating
• Meets MIL-P-17091B fastener standard for dimensional and material consistency
• Tensile strength of 16,500 psi for reliable hold in light-duty board mounting
• Bright, uncoated finish with tight length tolerance of plus or minus 0.005 inches

Compatibility

Designed as a standard 4-40 male-female hex nylon standoff for use in circuit board assemblies requiring non-conductive spacing hardware conforming to MIL-P-17091B specifications.

Installation Notes

Installation is performed by electronics technicians or qualified service personnel. Power down and de-energize all equipment before handling circuit boards or replacing standoffs. Use a hex wrench or nut driver sized for 3/16 inch across flats to avoid stripping the nylon body. Do not overtighten, as nylon threads can shear under excessive torque.
